    1478 Words  | 6 Pages

    divide, a cell must grow, replicate its genetic material (DNA), and split into two daughter cells. Cells perform these tasks in an organized series of steps that make up the cell cycle. In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase. • During interphase, the cell grows and makes a copy of its DNA. • The mitotic (M) phase, divides the cell DNA into two sets and its cytoplasm, forming two new cells. INTERPHASE

    a process of nuclear division among eukaryotic cells for which a couple of identical daughter cells are produced when the main parent cell divides. The focus point of mitosis is specifically the equal replication of genetic material within the nucleus that occurs through the function of this elaborate process is to keep a constant number of chromosomes in all somatic cells of the body. Mitosis is part of a bigger phase process known as the cell cycle, which is separated into two parts, mitosis and

  • Compare And Contrast Mitosis And Meiosis

    1130 Words  | 5 Pages

    contrast mitosis and meiosis. Mitosis and Meiosis both include splitting DNA between new cells. They both include cell reproduction which contains chromosomes from both parents. In Mitosis the two daughter cells are identical from a single parent cell. Mitosis produces the most cells in the body. In Meiosis the daughter cells are not identical and splits the chromosomes in half which produces gametes. This makes the cells identity unique. 2. What major event occurs during interphase? DNA replication

  • The Importance Of Cells In The Human Body

    970 Words  | 4 Pages

    There are more than 60,000 billion cells that make up the human body, they are the units that make up the tissues which make up our organs. When it is needed, the cells split into two and replace the ones which have come to their death, this makes it possible for our tissues to preserve their shape and their respective function with the passage of time. Every cell is therefore programmed to multiply and die. In order to multiply, the cell goes through a cycle whereby it completes phases in order

  • Differences Between Mitosis And Meiosis

    2 Discussion Questions Mitosis and meiosis are the two noteworthy procedures by which eukaryotic cells duplicate. Look into the procedures of mitosis and meiosis. Consider the stages required in each and their inevitable products. How are the distinctions naturally critical with respect to development and proliferation? Be set up to talk about how life is reliant upon both sorts of cell multiplication. Meiosis is the procedure of two genes which originate from a mother and a father and the characteristics

  • Cell Division As A Eukaryotic Cell

    1474 Words  | 6 Pages

    Cell Division As a eukaryotic organism grows, cells divide and create new cells based on its DNA. This is called cell division. Cell division is the process when a parent cell divides into two or more daughter cells. Cell division occurs as part of the cell cycle. The two types of cell division processes are mitosis and meiosis. Mitosis is the process where somatic, or non-reproductive, cells are created, while Meiosis is the process that creates gametes, reproductive cells like sperm and eggs

    move from G0 to G1 of the cell cycle when they are induced by various stimulation. The second step is the proliferative phase, in which the mitogens aid the hepatocytes to progress from G1 phase to the mitosis process. The last step is the termination phase whereby cells stop to proliferate, this step is controlled by negative factors such as transforming growth factor beta (TGF-β) and activin. During these three phases, multiple growth factors and cytokines play a role in cell signalling pathways to
